If you're there in decent weather, a canal cruise through St. Petersburg really is an absolute must. There are boat tours going constantly. Just buy your ticket a few hours in advance and you'll get a seat. Tours last about 60-90 minutes and cost roughly $15 USD. This is a fantastic way to see the city and learn about all of its beautiful architecture in the process. Nothing better on a sunny day in Petersburg! #cruises #canals #russia #spb #stpetersburg
